Chemistry Form 4 Experiment 5.1 Better

For Aluminium, examiners love to ask: "Why does aluminium sometimes react less vigorously than expected?" The answer: Aluminium forms a thin, protective layer of Aluminium Oxide (Al₂O₃) on its surface. Sandpaper removes this layer.

Test the solid form of the compound (e.g., lead(II) bromide) by dipping electrodes into it and observing the ammeter. Heat the substance until it melts and repeat the test. chemistry form 4 experiment 5.1

Add water to one and cyclohexane to the other; shake and observe. Repeat using Naphthalene. Observation Results For Aluminium, examiners love to ask: "Why does
